Build and program this little GoPiGo to protect your wardrobe, your closet, or even your whole room! Hide GoPiGo behind a closed door and when the door is opened, it will attack your siblings, scaring them, and even taking a picture as trespassing proof!

Feel like you never get a heads up on a rainy day before you leave for school or work?

Use GrovePi to build a rain notifier. The project alerts you with a red glowing LED if you need to remember your umbrella because it the forecast calls for rain, or a blue LED will glow if it’s going to be blue skies (well, maybe still cloudy, but no rain in the forecast). You won’t have to check your phone or watch — just look at the light on your way out the door!
